Does your printer support duplex printing?
If not, you need two layouts, one for each side. You print side one, then flip the stock and reload in your printer and print the same records from the second layout.
My printer does support duplex printing. I just don't know how to set up the layout so that it knows that there are 2 sides and that it should print it that way. Your help is very appereciated!
Assuming that this is standard sized sheets of perforated stock that you separate into multiple cards per page, I don't think that you can use duplex printing to get this to work--but I don't have such a printer to experiment with so I could be wrong about that.
